BAN D-TIGHTENER.

Togall whomit may concern:

Be it known that 1, JOHN REID, of the town of Almonte, in the county of Lanark, Province of Ontario and Dominion of Canada,- mechanic, have invented a new and useful Improvement in Bahd-Tighteners, of which the following is a specification.

My invention relates to band-tighteners, designed more particularly for spinning-maand it consists in the employment of double-grooved pulleys carried by pivoted counterweighted levers.

In the drawings, Figure 1 is a top plan view of a part of aspinni-ng-framc with my improvements applied thereto; Fig. 2, a side view of the same, partly in section; and Fig. 3 shows a spindle detached.

A indicates a framing, at both ends of which are upright-s B, those at one end carrying a 1 shaft-,"fifaud'drmn I), n iule those at the'ior ward end carrya cross-arm, E. v FF arethe spindles to be driven, having their lower ends stepped in the frameA and their upper ends passing through the cross beam E. as shown in .Figs. 2 and 3. The

spindles F are each provided with a grooved pulley, G, keyed or otherwise firmly secured Y H H indicate the.bands which'pass around the pulleys G and also around the drum D and The band II passes around the drum D, crosses itself, passes about opposite sides of grooved wheel I and about the wheel G on the ,spindle F. The band H "takes a similar course, passes about drum Dicrosses itself, passes on opposite sides of wheel 1 and around wheel G on spindle F, as shown.

' a Y The tight-ener-pulleys I l are ens-h made double --that is to say, each is providedwith :two complete annular grooves-as shown in Fig. 1. and each is carried at the end of a .pivoted lever, J J, carrying at its other end weights K K.

The lever J is'pivoted on a shaft, (1, onthe upper side of the frame A, in advance .of the lever J, and has arcarwardly-extending arm, b, to which its counter-weight K is attached. Theleverialso extends upward a considerable distance, so as .to'bring the center of its pulley I about in line with the pulley G on the shaft of spindle F.

I am aware that it has derstood as claiming such idea, broadly.
